ABSTRACT:
A process for the simultaneous production of synthesis and methanol or ammonia in which a modified blast furnace or vertical shaft furnace using iron ore and coke, or coal, is blown with oxygen or an oxygen-air mixture containing carbon dioxide to provide a top gas comprising essentially carbon monoxide which is at least partly shifted with steam to make hydrogen and carbon dioxide, which carbon dioxide is removed by compression and a solvent based carbon dioxide removal process, and the remaining gas stream is heated and passed through a systhesis reactor so constructed to recover heat from the synthesis reaction.
